T 0 all whom it may concern:

Be it known that 1, WILLIAM A. CRAW- ronn-Fnosr, a citizen of the United States, residing at Baltimore, in the county of Baltimore City and State of Maryland, have invented new and useful Improvements in House-Cooling and Lawn-sprinkling Devices, of which the following is a specification.

This invention relates to an improved house cooling and lawn sprinkling device and one object of the invention is to reduce the temperature of a building by sprinkling water upon the roof of the same thereby cooling the roof and subjacent parts by contact with the cooling liquid and by evaporation of the latter.

A further object of the invention is to utilize the water thus applied to the roof for the purpose of sprinkling lawns and flowers, thereby avoiding unnecessary waste.

A still further object of the invention is to raise the temperature of hydrant water used for sprinkling lawns and flower beds by previously passing the same over a heated surface exposed to the sun.

A still further object of the invention is to utilize for roof and lawn sprinkling purposes hydrant water reviously passed through a hot water heating system including radiators which will thus, as well as the supply pipes, be filled with water of a com paratively low temperature whereby the interior of a house equipped with such system will'be maintained at a relatively low temperature.

Still further objects of the invention are to simplify and im rove the construction and operation of t e class of devices to which the invention belongs.

, With these and other ends in view which will readily appear as the nature of the invention is better understood the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being however understood that no limitation is necessarily made to the recise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings: Figure 1 is a vertical sectional view showing a building equipped with a hot water heating system and to which the invention has been applied. Fig. 2 is a similar view of abuilding not equipped with a hot water heating system, but to which the invention has been applied.

Corresponding parts in both figures are denoted by like characters of reference.

Referring more particularly to Fig. 1 of the drawings, 55 represents the walls, 6, the roof, and 7-7, the horizontal partitions constitutin the floors and ceilings of a building of any suitable construction wherein is installed a hot water heating system including radiators A, a heating coil B arranged at the fire place of a heater C, an expansion tank D and valved service pipes such as are usually employed in a system of this kind and including the supply pipe 8 having a stop cock 9 controlling the supply to the heating coil B, and the expansion pipe 10 leading to the tank D and having a stop cock 11 adjacent to said tank.

A pipe or duct 12 having a stop cook 13 leads from the pipe 11 through the roof of the house adjacent to which the said pipe may be provided with one or more sprinklers S of any suitable approved pattern, either rotary or stationary, said sprinklers being so disposed that water ejected therethrough will fall upon a portion of the roof. It is obvious that the water before reaching the sprinkler must pass through the entire heating system including the radiators A. The pipe 8 is to be connected with any suitable source of supply, not shown in the drawings,

which may be the city water system or any other individual or public source of supply. Supported adjacent to the caves of the roof are the usual gutters 14 for catching the water discharged over the roof, and connected with said gutters to receive the discharge therefrom are the stand pipes or spouts 15 which are equipped with fixtures 16 having valves 17. and adapted for the attachment of hose 18 with which a sprinkler 19 of any suitable kind may be connected for the purpose of sprinkling lawns, flower beds and the like; the sprinkler 19'may of course be omitted and an ordinary nozzle substituted, if desired.

In Fig. 2 of the drawings the installation is precisely the same as already de scribed with the exception that the hot water heating system .is omitted, the pipe 12 leading through the roof 6 being a branch of the supply pipe 8.

It will be readily seen from the foregoing description taken in connection with the drawings hereto annexed that whenever it shall be rendered desirable in hot weather,

Water may be sprinkled upon the roof for the purpose of cooling the same. and incidentally reducing the temperature of the interior of the house while the portion'of such.

flowersvare frequently injured rather than benefited by the application of water at a too low temperature. When the invention during the hot summer is used in connection with a building having a hot water heating plant installed therein, an additional and very important advantage results from the fact that Whenever the device is in operation Water at a relatively low temperature may be drawn through the pipes of the heating system including the radiators which will thus be materially cooled and rendered effective in reducing the temperature of the apartments Where they are located.

It may he sometimes found desirable to establish in connection with the hot water heating system a cooling tank T located at the top or head of the system, the contents of which may have its temperature artificially reduced by the direct application of ice or by a packing of ice, salt, cooling liquids and the like. When such an installation is used,.the heating plant may during hot weather be utilized for cooling purposes by establishing therethrough a downward circulation through a pipe 35 having a valve 36 of water the temperature of which has been artificially reduced so as to render it highly effective in reducing the temperature of the apartments where the radiators of the system are located.

Having thus described the invention what is claimed is 1. A device of the. character described, comprising a hot water heating system including an expansion tank and a pipe connecting such tank with the remainder of the system, a branch pipe connected with the expansion pipe and carrying a sprinkler, means including a roof, a gutter and a spout for collecting the Water discharged through the sprinkler, and a valved coupling fixture upon the spout.

2. A devlce of the character described, including a hot water heating system, a pipe connected therewith and carryinga sprinkler, and means for gathering and subsequently utilizing the water ejected through the sprinkler, said means including a roof and a gutter.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM A. CRAWFORD-FROST.
